Implicit large-eddy simulations of a deep cavity at Mach 0.8 and a Reynolds number based on a cavity length of 860,000 were conducted using a modified high-resolution implicit large-eddy-simulation method. The object of the paper is to assess the capability of the modified numerical method compared to large-eddy simulation with a selective mixed-scale model and experimental measurements of the mean flowfield, Reynolds stresses, and pressure spectra. The frequency and amplitude of the fundamental modes are predicted to within 2% and 6 dB at all grid levels. There is excellent agreement of the mean flowfield and Reynolds stresses, demonstrating that there is no need for an explicit subgrid model when using the new reconstruction method for this flow configuration.
